IMPLEMENTATION TO ENHANCE SECURITY OF RFID CARD

VLSI AND EMBEDDED

Unauthorized money transaction is a very big problem. The main aim of the proposed system is to build a system that defends against unauthorized transaction in RFID. Although a variety of security solutions exist, many of them do not meet the constraints and requirements in terms of efficiency, security, and usability. In an attempt to address these drawbacks, the proposed system is used. In the proposed system on the server side a secure transaction verification scheme is designed which decides whether to make transaction successful or block the card. Many researchers proposed different techniques for unauthorized transaction but all of them required some auxiliary devices to carry with users. In the proposed work there is an interrogation session between reader and user with addition of extra security for secure transaction and according to the behaviour of the transaction theft can be determined.
